Abstract (en)
[origin: WO8707637A2] Lubricating oil and functional fluid compositions having improved high temperature stability and which contain at least one phosphorus-containing composition and at least one oil-soluble nitrogen-containing composition. More particularly, the lubricating and functional fluid compositions of the present invention comprise (A) a major amount of an oil of lubricating viscosity, and a minor amount of (B-1) at least one soluble amine salt of at least one substituted phosphoric acid composition characterized by formula (I), wherein R<1> is hydrogen or a hydrocarbyl group, R<2> is a hydrocarbyl group, and both X groups are either O or S, and (C) at least one soluble nitrogen-containing composition prepared by the reaction of a hydrocarbon-substituted succinic acid-producing compound with at least about one-half equivalent, per equivalent of acid producing compound, of an amine containing at least one hydrogen attached to a nitrogen atom. Preferably, the amine salts of the phosphoric acids utilized in the lubricating compositions of the present invention are derived from primary amines, and the soluble nitrogen-containing compositions (C) also contain boron. The lubricating compositions of the present invention are particularly useful in gear applications requiring high thermal stability such as from about 160 DEG C with intermittent operation up to about 200 DEG C.
